Abstract
I’ve written a new LISP TRACE package which supersedes the current TRACE package. Briefly, it differs from the basic LISP trace package by: (a) having a clearer, indented printout format; (b) allowing a variety of information to be suppressed or printed when a function is traced; (c) allowing a user to break a function or to suppress the tracing when a particular condition is met; (d) modifying edit[l] and grindef[l] to be compatible with traced functions; and (e) has a PRINTLEVEL control.
